7.2 Cross-Platform Issues for NSS Volumes

If you plan to move NSS pools and volumes cross-platform between NetWare and Linux servers, consider the following guidelines:

7.2.1 Guidelines for File Systems on Linux Servers

OES 2 Linux requires a Linux POSIX file system volume for the operating system, such as Ext3. The following guidelines apply:

  • You cannot install the Linux operating system on an NSS volume.

  • Use NSS on Linux only as data pools and volumes.

  • You cannot SAN boot Linux cross-platform.

  • You cannot move Linux POSIX file systems cross-platform to a NetWare server.

  • You can move NSS volumes cross-platform to a Linux server.

  • NSS volumes that were originally created on NetWare can be moved cross-platform from NetWare to Linux. If both platforms support the same media format, Linux volumes can be moved cross-platform from Linux to NetWare.

7.2.2 Guidelines for File Systems on NetWare Servers

NetWare uses an NSS pool (sys) and volume (sys:) for the operating system. Upgraded NetWare systems can optionally keep a NetWare Traditional volume as the system volume. The following guidelines apply:

  • You cannot install the NetWare operating system on a Linux POSIX file system volume or on an NSS volume on Linux.

  • You cannot create or mount Linux POSIX file systems on a NetWare server.

  • You cannot SAN boot NetWare cross-platform.

  • You should not move an NSS system volume from NetWare to Linux unless you intend to use it as a data volume (or not at all) while it is mounted on the Linux server.

  • If you move an NSS system pool cross-platform, any volumes it contains function as data volumes on Linux, including the sys: volume.

  • You can create an NSS data volume on NetWare, and then move the volume cross-platform to Linux.

  • If you use shared pools in a cluster, only pools that are originally created on NetWare can be migrated or failed back from Linux to NetWare. Mixed-platform clusters are supported only for rolling cluster conversions from NetWare to Linux.
